Diversity of Life

The classification of living organisms includes a variety of distinct groups, each with unique characteristics. Chordates are noted for features like a dorsal nerve cord and notochord, while annelids possess a closed circulatory system and segmented bodies.

Mammalia: Bear

Terrestrial Adaptations -Hair To Keep Warm -Milk To Nourish Offspring -Endothermic: Maintain High Temperature

Placental Mammals

Reproduction Strategy -Offspring develop completely inside mothers body -Offspring grow inside of mothers placenta The Placental mammal reproduction strategy is superior to the reproducton of marsupials, because offspring are able to develop completely inside of mothers body, unlike marsupials where they are born immature. Since they are, born more mature they have higher chances of survival.

Primates

Gorilla

Marsupials

Reproduction Strategy -Embryos are born immature -Embryo completes development in a pouch outside of mothers body The Marsupial reproduction strategy is superior to the reproduction strategy of monotremes, because monotreme offspring are less likely to survive due to the fact that eggs are harder to protect than embryos in a mothers pouch. Marsupial offspring are

Fungi
Chytridiomycota

Can reproduce both sexually, and asexually. For asexual reproduction, the sporangia release zoospores, that germinate into sporophytes. For sexual reproduction, sporangium germinates which releases haploid zoospores, which germinate into gametophytes. After it matures, it combines with a female gamete, to make a zygote.

Allomyces

Basidiomycota (Club Fungi)

Reproduces both sexually, and asexually. Reproduces asexually, like other fungi, when cells split apart, to create a copy of the fungus. In sexual reproduction, mycelia of different mating strains combine to create mycelium with basidiospores, which then form a mushroom.

Agaricomycetes

Deuteromycota (Imperfect Fungi)

The sexual reproduction of Deuteromycota has never been observed, however they do reproduce asexually. Deiteromycota undergoes sporogenesis like other fungi, when cells split apart, and create a copy of the fungus.

Aspergillus niger

Ascomycota (Sac Fungi)

Reproduces asexually or sexually. In axexual reproduction the fungus undergoes fission, and cells split apart, to create a copy of the fungus which can split apart. The spores formed by asexual reproduction are called conidia. In sexual reproduction, two gametes have to combine.

Pezizomycotina

Zygomycota

Reproduces Asexually or Sexually. In asexual reproduction, hyphae produce sporangium, which burst to release spores, which then germinate and produce more fungi. In sexual reproduction, gametes form at the top of hyphae, and combine with each other to reproduce.

Rhizopus stolonifer

Plantae
Angiosperms

Angiosperms successfully adapted from water to land, through adaptations such as, a good reproductive strategy which uses insects to transfer pollen.

P. Anthophyta (Flowering Plants)

Helianthus annuus

Gymnosperms

Gymnosperms successfully adapted from water to land through adaptations such as, a good vascular structure to stand upright, and a waxy cuticle to retain moisture. Gymnosperms are also good at reproducing as they use wind to reproduce.
